Use of golden mushroom in animal production

From the paper

Abstract

The invention relates to an application of flammulina velutipe powders in animal production, which belongs to the field of microbe making. The flammulina velutiper powders adopt the following fermentation medium formula with Flammulina velutipes (Fr.)Sing.As5.632 as the production strains to carry out the liquid submerged fermentation: the formula of the medium per liter is as follows: 20g of bran, 5g of corns, 10g of sucrose, 50g of soybean powders, 1g of monopotassium phosphate and 0.5g of magnesium sulfate are added with water to the constant volume of 1 liter the inoculum concentration is 5 to 10 percent, the medium volume accounts for 60 to 70 percent of the volume of a fermentation tank, the fermentation temperature is 22 to 25 DEG C, the ventilation volume is 1:0.04 to 1.0, the medium is scaled up by passing through a shake flask, a liquid seeding tank and a liquid fermentation tank, and the fermentation time of each stage is 72 to 120 hours the fermented fermentation liquid is filtered and concentrated, then the concentrated liquid and the filtering wet mycelium are dried and crashed. The flammulina velutiper powders which are produced by the invention can be widely applied to the feed industry, and can markedly improve the immunologic functions of the domestic animals and reduce the amount of antibiotic without any side effect, while improving the growth of the animals, and reduces the death rate.
